Guild Wars 2

They are all over the place.
Where are these being shot off from?
As we already know these were created by the Tower.
“The Tower of Nightmares is also creating smaller offshoots of itself
at several locations around the map.”
Now that the tower is destroyed how are they still being created?
Is there another tower of nightmares that we are
not aware of?

i think lore-wise you’re supposed to just consider them “rogue spores” that took longer to grow.

Not if they work like they have up to this point. The events always started with a windblown spore crashing into the ground.

In Kessex Hills, one of the NPCs stated that offshoots are spawning from the roots of the original tree still. Not sure how, tbh, and the old animation of a giant spore falling to the ground is still there. But that’s the explanation.

I’m not sure if the dialogue is still there after this update though. I believe it was Scholar Ela Makkay who said such, and the dialogue isn’t up on the wiki…

The Tower Of Nightmares appears to either be a small shrub or a plant that was not designed to grow to such a height unaided (in the wild it might require a tall tree for support). Hence not only the Tower but also the offshoots are supported by a frame in like manner to the Tower itself. Anyhow, the shoots may form in any number of ways – they may sprout from the remaining roots of the Tower or from the remaining spores released by the Tower and/or it’s offshoots. This seems fitting, since plants in real life often do the same thing.

The tower(s) were defensive structures to protect the plant – and the offshoots. It was the main part of the events during the Tower of Nightmares release, where everyone said “these explosives/mortars/golem can take out those weaker offshoot’s defenses, but it cannot penetrate the giant tower’s” more or less.

It’s defense, not stability. And in the case of the main tower, general housing as well.
